Abstract (en)
[origin: WO2015165706A1] The invention relates to a machining tool for machining bores, comprising a main part (3) which has a central axis (5) in a circumferential surface (7), at least two geometrically defined cutting edges (9/1 to 9/5) which are unevenly distributed on the circumferential surface (7) of the machining tool (1) when seen in the circumferential direction of the machining tool (1), and a number of guide strips which project from the circumferential surface (7) of the main part (3). The machining tool (1) is characterized in that two guide strips (19/1, 19/2) are designed to be stationary and are arranged with a circumferential spacing of less than 180° relative to one another such that a first circumferential region (21/1) is formed which lies between the stationary guide strips and extends over more than 180°, and a second circumferential region (21/2) is formed which extends over less than 180°; such that one (9/1, 9/2) of the at least two cutting edges (9/1 to 9/5) is arranged in the second circumferential region (21/2) between the stationary guide strips (19/1, 19/2); and such that at least one guide strip (23) is spring-mounted on the main part (3), and the at least one spring-mounted guide strip (23) is arranged in the first circumferential region (21/1) such that the at least one spring-mounted guide strip (23) resiliently presses the machining tool (1) against the stationary guide strips (19/1, 19/2) when machining a bore.
